Snapshots of flare evolution observed in the AIA 335 Å passband (a–d), and background-subtracted AIA 335 Å intensity profiles summed over specified regions (e). Shown are the whole flare-hosting AR (enclosed by the brown box in panel d), the main flare region (outlined by the green box in panel c), and the late-phase loop region (outside the main flare region, but within the AR). For comparison, the background-subtracted line irradiance in EVE 335 Å is also overplotted as the dashed line in panel e.
